Artificial clouds were recently made
for the protection of vines from frosts at
Pagny, on the Franco German frontier.
! Liquid tar was ignited IN tin boxes and
pieces of solid tar on the ground near the
vines. Large clouds Of smoke arose and
protected the vineyard for two hours.
Although vines in the neiglbO-lOOd were
injured by the frost, ell that remained
under the clouds We're left unln 5ured OF
